DETAILED DESCRIPTION OF THE EMBODIMENTS

Although the conventional human-computer interaction mode can realize the human-computer interaction function to a certain extent, due to the single interaction mode, certain specific pose actions need to be pre-defined. The interaction process is not very natural, and to a certain extent, which brings inconvenience to the user when performing operations.

In order to illustrate objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and not to limit the present application.

Methods for a human-computer interaction in a display device provided in this application can be applied to an application environment as shown in FIG. 1. A user appears within a visual angle range of a display device. The display device (television) obtains current image data of the user. When detecting that the user is in a front-view state, multiple different candidate data are displayed in different display areas. The user browses the candidate data in the display device. The display device recognizes a target display area where the user is gazing. The display device reads the candidate data corresponding to the target display area, and performs an operation corresponding to the read candidate data. The display device may specifically be a television, a tablet computer, a tiled display device, a vehicle-mounted display device, or the like.

In an embodiment, as shown in FIG. 2, a method for the human-computer interaction in a display device is provided. Taking the method applied to a display device as an example for description, the method includes the following steps:

S200: obtaining current image data of a user.

The display device may obtain the current image data of the user by means of a camera built-in or external to the display device. Specifically, the camera can be provided on the display device. The camera can be rotated by 360 degrees to capture images of the user and obtain the current image data of the user. Furthermore, the camera can be provided directly in front of the display device. The camera acquires the current image data of the user who enters the visual angle range of the display device.

S400: when detecting that the user is in a front-view state, displaying multiple different candidate data in different display areas.

A front-view recognition is performed on the current image data of the user obtained in step S200. When detecting that the user is in the front-view state, the multiple different candidate data are displayed in the different display areas. For simplicity, “front-view recognition” here can be understood as a “switching” action. When detecting that the user is in the front-view state, the display device immediately displays the multiple different candidate data in the different display areas. Furthermore, the detection can be performed by comparing the current image data of the user with historically obtained image data of the user in the front-view state. In practical applications, front-view image data of the display device in the front-view state acquired by an image acquisition device is first obtained. The front-view image data of the display device in the front-view state can be the data acquired in a historical record or the data acquired on the spot. The image acquisition device can be a camera or the like. Here, the front-view image data of the display device in the front-view state is acquired by the image acquisition device. The image acquisition device can be provided on the display device, or on an auxiliary device or a peripheral device of the display device. For example, when the device is a television (TV), the image acquisition device can be provided on the TV or on a set-top box that is matched with the TV. More specifically, after performing image processing and image target coordinate conversion on the front-view image data of the display device in the front-view state captured by the camera, a relative position of the device and the user's face can be determined. That is, face image data of the user in the front-view state of the display device can be obtained. The determination that the display device is in the front-view state can be achieved by using techniques such as head pose estimation or gaze tracking.

S600: recognizing a target display area where the user is gazing.

Adopting techniques such as head post estimation and gaze tracking can accurately identify the target display area where the user is gazing. Specifically, different data is displayed in the different display areas on the display device. The user directly gazes (watches) the target display area according to his own needs when browsing the theses data. In practical applications, the position where the user is gazing can be recognized based on the gaze tracking technology. Staying time of the user's gaze in each display area is cumulatively counted. The candidate display area corresponding to the staying time that firstly and cumulatively exceeds a preset gazing time threshold is selected as the target display area where the user is gazing. For example, as shown in FIG. 3, currently, three display areas on left, middle, and right of the TV show contents of “call the granddaughter, the eldest son, and the younger son”. The user has been gazing the middle display area for the longest time. That is, the target display area where the user is gazing is recognized as the middle display area.

S800: reading the candidate data corresponding to the target display area, and performing an operation corresponding to the read candidate data.

The relationship between each display area and the corresponding data is stored in the display device. After the target display area is determined in step S600, the display device directly reads the stored candidate data corresponding to the target display area, runs the candidate data, and performs corresponding operations. Based on taking the embodiment shown in FIG. 3 as an example, after determining that the middle display area is the target display area in step S600, the display device reads the data of “call to an eldest son” and performs the operation of“call to eldest son”. Optionally, when the display device does not have a communication function, a peripheral device (a communication device) can be controlled to perform the operation corresponding to the read candidate data.

In the above-mentioned method for the human-computer interaction in the display device, the display device obtains the current image data of the user. When detecting that the user is in the front-view state, the multiple different candidate data are displayed in different display areas. The user browses the candidate data. The display device recognizes the target display area that is being gazed, reads the candidate data corresponding to the target display area, and performs the operation corresponding to the read candidate data. In the whole process, user's needs can be perceived without excessive operation, which realizes a convenient human-computer interaction, and brings convenient operation to users.

As shown in FIG. 4, in one of the embodiments, after step S800, the method further includes:

S900: when detecting that the user is not in the front-view state, interrupting the operation corresponding to the read candidate data.

When the display device detects that the user is not in the front-view state, the operation corresponding to the read candidate data is interrupted. Continuing to take the embodiment shown in FIG. 3 as an example, during that the TV is performing the operation of calling to the eldest son, when detecting that the user is not in the front-view state, the operation is interrupted. Optionally, step S900 may be performed within a limited time range. That is, when detecting that the user is not in the front-view state within a limited time range (for example, 10 seconds), the operation corresponding to the read candidate data is interrupted, so the user does not have to maintain the front-view state for a long time, which brings convenience to users. When the user wants to end the current operation, the user can be in a “non-front-view state” with the display device. When detecting that the user is not in the front-view state, the TV will interrupt the current operation. For example, the user currently wants to end the call with the eldest son, and the user will turn his head away, such that the TV recognizes that the user is not in the front-view state, and interrupts the call with the elder son.

As shown in FIG. 4, in one of the embodiments, S400 includes:

S420: when detecting that the user is in the front-view state, counting time for which the user is in the front-view state;

S440: when the time for which the user is in the front-view state exceeds a preset time threshold, displaying the multiple different candidate data in the different display areas.

Here, as for the front-view state, the requirement for the preset time threshold is further introduced. Only when the user is in the front-view state for more than the preset time threshold, the multiple different candidate data will be displayed in the different display areas. The user gazes at the TV (in the front-view state) for a certain time (3 seconds), and the TV displays the different candidate data in the different display areas. By adopting the above-mentioned method, misoperation of the user during daily use can be avoided, bringing convenience to the user.

In one of the embodiments, when detecting that the user is in the front-view state, the displaying the multiple different candidate data in the different display areas includes: according to the current image data of the user, adopting a front-view recognition technology to preliminarily detect whether the user is in the front-view state; when the preliminary detection result is that the user is in the front-view state, acquiring the face image of the user; according to the face image of the user, performing recognition processing; according to the recognition processing result, displaying the multiple different candidate data in the different display areas. The recognition processing includes at least one of a face recognition, an age recognition, an facial expression recognition, and a gender recognition.

In this embodiment, the front-view recognition, combined with the face recognition, or the age recognition, or the facial expression recognition, or the gender recognition is adopted to more accurately display the interaction data of the user. Specifically, firstly according to the current image data of the user, the front-view recognition technology is adopted to preliminarily determine whether the user is in the front-view state. When the user is in the front-view state, the face image of the user is acquired. At least one processing of the face recognition, the age recognition, the facial expression recognition, and the gender recognition is performed on the acquired frontal face image. According to the processing result, the multiple different candidate data are displayed in the different display areas. For example, when based on the front-view recognition combined with the face recognition, the user's identity is recognized, and the candidate data associated with the user's identity, such as the user's address book, and avatars of the user's relatives, can be displayed in different display areas. When based on the front-view recognition, combined with the face recognition and the facial expression recognition, the user's identity is recognized, and it is preliminarily recognized that the user has a happy facial expression at present, the candidate data associated with the identity and in which the user is interested, such as user's favorite TV programs, user's favorite pictures, photos, and the like, can be displayed in the different display areas.

In one of the embodiments, the above-mentioned method for the human-computer interaction in the display device further includes: when a size of the face image of the user is greater than a preset face image size threshold, displaying the multiple different candidate data in the different display areas.

As a distance between the user and the display device is different, the size of the face image of the user in the user's images acquired by the display device is different. In addition, the human-computer interaction is effective only when the user is within a certain distance from the display device. For example, during that the user performs the human-computer interaction with the TV, if the user is tens of meters away from the TV, the human-computer interaction between the user and the TV is obviously an invalid human-computer interaction action. In this embodiment, based on the above-mentioned principles and actual application requirements, only when the size of the user's face image is greater than the preset face image size threshold, the multiple different candidate data can be displayed in the different display areas. The preset face image size threshold can be a face image acquired when presetting the distance between the user and the display device, for example, an acquired face image pre-acquired when the user is 3 meters away from the TV device, the size of corresponding frontal face image is obtained as the preset the face image size threshold.

In one of the embodiments, the when the preliminary detection result is that the user is in the front-view state, acquiring the face image of the user includes: when the preliminary detection result is that the user is in the front-view state, performing the face recognition on the user; and when recognizing the user as a known legitimate user, acquiring the face image of the user.

When detecting that the user is in the front-view state, the face recognition is performed on the user to determine whether the user is a known legitimate user. When the user is a known legitimate user, the frontal face image of the user is acquired. In this embodiment, a dual mechanism combining the front-view recognition and the user identity recognition is adopted to identify whether multiple different candidate data needs to be displayed in different display areas, so as to avoid misoperation and bring convenience to the user.

In one of the embodiments, the above-mentioned method for the human-computer interaction in the display device further includes:

When recognizing the user's identity by the face recognition, displaying multiple different candidate data associated with the user's identity in the different display areas.

The candidate data is associated with the user's identity. For example, when recognizing the user's identity, multiple contact information associated with the user can be displayed in the different display areas. For example, the contact information of the daughter, the son, and the mother can be displayed in the three display areas on the left, middle, and right.

In one of the embodiments, the recognizing the target display area where the user is gazing includes: adopting a head pose recognition technology to confirm an orientation and an angle of the user's head; according to the orientation and the angle of the user's head, recognizing a display area being browsed by the user, and using the display area being browsed by the user as the candidate display area; respectively counting the staying time of the user gaze in the different candidate display areas; selecting the candidate display area with the longest staying time as the target display area where the user is gazing.

It should be understood that, although the various steps in the flowcharts of FIGS. 2 and 4 are displayed in sequence as indicated by arrows, these steps are not necessarily performed sequentially in the order indicated by the arrows. Unless clearly illustrated herein, performing these steps is not strictly restricted in order, and these steps can be performed in other orders. Moreover, at least part of the steps in FIGS. 2 and 4 may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily performed at the same time, but can be performed at different times. These sub-steps or stages are not necessarily performed in sequence, but can be performed in turn with or alternately with at least part of other steps, or sub-steps or stages of the other steps.

In order to further explain the technical solutions and effects of the method for the human-computer interaction in the display device of the present application in detail, the detailed description will be made below by taking the application to the TV as a specific application example, in conjunction with FIGS. 3, 5, 6, 7 and 8. When applied to the TV, the method for the human-computer interaction in the display device of this application includes the following steps:

2. The TV determines whether the user is in the front-view state according to the acquired image data of the user, the details are as shown in FIG. 5 and FIG. 3. The user is frontally facing the center of the TV. The TV detects that the user is in the front-view state, and multiple different candidate data are displayed in different display areas on the TV. Specifically, three contacts of the granddaughter, the eldest son, and the younger son are displayed on the left, middle and right of the TV, and voiceover or explanatory data is displayed in other blank areas (this part of the content may not be implemented).

3. As shown in FIG. 6, the user slightly swings his/her head left and right to select one of the contacts by gazing at it. A video call can be made after staying there for 3 seconds. The TV adopts a dual recognition mechanism combining the front-view recognition and the user's identity recognition to identify that the current user is a legitimate user, and that the target display area where the user is gazing is the left area.

4. The TV reads the candidate data corresponding to the left area and performs the corresponding operation. As shown in FIG. 7, the TV reads the data related to the granddaughter's video call and starts a video call with the granddaughter.

5. As shown in FIG. 8, when the video call is connected, the image of the video call is displayed on the TV. When the user needs to interrupt or end the video call, the user can turn his/her head and gazing at the TV sideways. The TV detects that the current user is in the non-front-view state and then ends the video call.
